The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

This species was fairly abundant in a February sample of the upper Yakima.
27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Case view of a Lepidostoma (Lepidostomatidae) (Little Brown Sedge) Caddisfly Larva from Mongaup Creek in New York
This one got a little bit damaged in the abdomen when I extracted it from its case. That's a delicate job.

It may be Lepidostoma. It appears to be lacking a dorsal hump, and the genus is quite large. The cases can be highly variable and can be made of sand or organic materials.

the case and legs support your conclusion that this is lepidostomatid. A limnephilid would have a different arrangement of the setae/spines on the legs.
